【摘要】：永磁調(diào)速器以磁力耦合技術(shù)為基礎(chǔ)，利用導(dǎo)體轉(zhuǎn)子在永磁轉(zhuǎn)子所激發(fā)的磁場(chǎng)中做旋轉(zhuǎn)運(yùn)動(dòng)，從而在兩轉(zhuǎn)子間的空氣氣隙處產(chǎn)生交變磁場(chǎng)，以使電機(jī)與負(fù)載實(shí)現(xiàn)無接觸且高效率運(yùn)轉(zhuǎn)。作為一種新興調(diào)速設(shè)備，永磁調(diào)速器以其卓越的技術(shù)優(yōu)勢(shì)被大量工程人員所熟知，并在越來越多的場(chǎng)合得到應(yīng)用。目前對(duì)永磁調(diào)速器的研究主要體現(xiàn)在應(yīng)用及節(jié)能效果方面，對(duì)于永磁調(diào)速器工作機(jī)理中所涉及的磁場(chǎng)分布問題卻鮮有研究。 本文從電磁場(chǎng)的理論出發(fā)，針對(duì)兩種不同結(jié)構(gòu)的永磁調(diào)速器磁場(chǎng)問題，結(jié)合不同結(jié)構(gòu)的磁場(chǎng)工作機(jī)理，分別通過理論方法進(jìn)行了磁場(chǎng)分析，并基于理論分析結(jié)果，，運(yùn)用ANSYS軟件中的電磁場(chǎng)分析模塊對(duì)不同結(jié)構(gòu)永磁調(diào)速器進(jìn)行建模，求解出其工作磁場(chǎng)的分布及參數(shù)值，驗(yàn)證理論分析結(jié)果的正確性，為永磁調(diào)速器的磁場(chǎng)研究提供了理論依據(jù)。同時(shí)，利用ANSYS分析了不同結(jié)構(gòu)參數(shù)對(duì)永磁調(diào)速器磁場(chǎng)的影響，為永磁調(diào)速器的優(yōu)化設(shè)計(jì)提供了有力參考。最后，在前面分析結(jié)果的基礎(chǔ)上提出了一種新型永磁調(diào)速器的結(jié)構(gòu)，并對(duì)其磁場(chǎng)進(jìn)行了簡(jiǎn)單分析，驗(yàn)證了此結(jié)構(gòu)的合理性。 通過對(duì)兩種不同結(jié)構(gòu)永磁調(diào)速器磁場(chǎng)的分析，得出了筒形永磁調(diào)速器的磁場(chǎng)分布明顯優(yōu)于圓盤式永磁調(diào)速器，在相同的結(jié)構(gòu)參數(shù)下，根據(jù)磁場(chǎng)分析結(jié)果可以得出，筒形永磁調(diào)速器中工作磁場(chǎng)的強(qiáng)度更高，其永磁轉(zhuǎn)子上所獲得的輸出扭矩更大，效率更高。其次，通過ANSYS對(duì)不同轉(zhuǎn)速下的磁場(chǎng)分布進(jìn)行了分析，結(jié)果表明：在相同的氣隙厚度條件下，隨著轉(zhuǎn)速的提高，工作氣隙處的磁場(chǎng)強(qiáng)度增大，從而拉動(dòng)永磁轉(zhuǎn)子的磁場(chǎng)力增大，使永磁調(diào)速器輸出扭矩不斷增大，效率也隨之提高。同時(shí)，由不同結(jié)構(gòu)參數(shù)下磁場(chǎng)的分析結(jié)果得到：永磁調(diào)速器結(jié)構(gòu)中的氣隙厚度與永磁體厚度對(duì)工作磁場(chǎng)的分布與強(qiáng)度影響最大。最后，對(duì)提出的新型永磁調(diào)速器結(jié)構(gòu)做了磁場(chǎng)分析，與前兩種永磁調(diào)速器的磁場(chǎng)分布相比，該新型結(jié)構(gòu)設(shè)計(jì)合理，并且具有一定的優(yōu)越性。
[Abstract]:The permanent magnet governor is based on the magneto-force coupling technique and uses the conductor rotor to rotate in the magnetic field excited by the permanent magnetic rotor, thus generating an alternating magnetic field at the air gap between the two rotors. In order to make the motor and load to achieve non-contact and high efficiency operation. As a new type of speed regulating equipment, permanent magnet governor is well known by a large number of engineers because of its outstanding technical advantages, and has been applied in more and more occasions. At present, the research of permanent magnet governor is mainly reflected in the application and energy saving effect, but there is little research on the magnetic field distribution involved in the working mechanism of the permanent magnet governor. In this paper, based on the theory of electromagnetic field, the magnetic field of two kinds of permanent magnet governor with different structures is analyzed by theoretical method, and the results are based on the results of theoretical analysis. The electromagnetic field analysis module in ANSYS software is used to model the permanent magnet governor with different structure, and the distribution and parameter value of its working magnetic field are solved. The correctness of the theoretical analysis results is verified, which provides a theoretical basis for the magnetic field research of the permanent magnet governor. At the same time, the influence of different structure parameters on the magnetic field of permanent magnet governor is analyzed by ANSYS, which provides a powerful reference for the optimization design of permanent magnetic governor. Finally, a new structure of permanent magnet governor is proposed based on the previous analysis results, and its magnetic field is simply analyzed, which verifies the rationality of the structure. By analyzing the magnetic field of two kinds of permanent magnet governor with different structure, it is concluded that the magnetic field distribution of the cylindrical permanent magnet governor is obviously superior to that of the disk permanent magnet governor. Under the same structure parameters, according to the result of magnetic field analysis, it can be concluded that, The working magnetic field of the cylindrical permanent magnet governor is higher, and the output torque of the permanent magnet rotor is higher and the efficiency is higher. Secondly, the magnetic field distribution at different rotational speeds is analyzed by ANSYS. The results show that the magnetic field intensity at the working air gap increases with the increase of the rotating speed under the same air gap thickness, thus the magnetic field force of the permanent magnet rotor increases. The output torque of the permanent magnet governor is increasing, and the efficiency is also improved. At the same time, from the results of magnetic field analysis under different structure parameters, it is concluded that the thickness of air gap and permanent magnet in the structure of permanent magnet governor have the greatest influence on the distribution and intensity of the working magnetic field. Finally, the magnetic field analysis of the structure of the new permanent magnet governor is made. Compared with the magnetic field distribution of the first two kinds of permanent magnetic speed governor, the new structure is reasonable in design and has certain advantages.
